Patented Apr. 25, 1933 PALMORE GREER, OF HIGGINSVILLE, MISSOURI NT OFFICE GARAGE Application filed` October 6, 1930. Serial No.486,654.

My invention relates to garages and more `particularly to privatel garages and elevators for moving an automobile to and from a 'ground floor level, the principal objects of the'invention being to provide a vertically 2movable platform for transferring an auto- -mobile between the ground surface and a basement :door level, to adapt a :movable platform to serve asa garage, and to effect op'- eration lofthe platform by the driving mechanism of the automobile'.

' In accomplishing these and other objects of my invention, I have provided improved details ofgstructure, the preferred form of which is illustratedl in the accompanying drawings, wherein: A

' Fig. 1 is a fragmentary perspective view of a building having, a roofed garage embodying my invention, part ofthe ground ad jacent thereto being broken away to illustrate one ofthe platform supporting posts.

VF ig. 4 is a section ,on the line4-4, Fig. 3.

' Referring in detail to thedrawings:

1 designates generally a building suchyas a residence including a wall l2 extended downwardly from the ground` 'surface to form the wall 3 of a basement having a door opening 4, and 5 designates the floor of the basement. Y v Y A pit sufciently large to accommodate an automobile is formed in communication with said basement wall opening comprising a floor 6 offset downwardly from the basement floor, vertical side walls 7 and 8, and a vertical front wall 9.

Front and rear pairs of vertical threaded posts 10, 11, 12 and 13 have lower ends fixed in the floor of the pit at the corners thereof in spaced relation with the pit walls, and spaced sufficiently to permit an automobile to pass therebetween, and a platform 14 vertically movable in the pit is provided with suitable openings for mounting the vsame 4and 31 Y vbrackets 32 and 33. fixed to the side frame channels are relatively long shafts .34 havl.

meshed with the bevel over the posts for support thereby and movement thereover as presently described. The platform includes side frame members'l and l'preferably comprising channels yhaving upper and lower flanges 17 and 18 presented toward the median line of the platform, similar channels 19 and 20 forming endl frame members fixed toV the side channels, and planks 21 mounted on thel upper edges for 'supporting an automobile or the like.

Bevel gears-23 having internal threadsfor mounting the same -on the threaded posts are locatedbetween the flanges of the channels at'the corners of the vided with collars 24 having ends rotatively abutting the lower ends oftubular posts or e standards 251 extending in said platform openings and upwardly, from the platformho and fixed thereto byfcollar-lilre clamping members l26 and 27. The platform is then supported from the rotative beveled gears,

and the standards will telescope freely over the threaded posts `when the platform is lowered. Y l

Mounted in pairs of aligned-bearings 30 projecting from laterally extending their inner or rear ends gears 23 on thepair of threaded postsadjacent the building,and bevel gears 36 at their frontends meshed ing bevel gears 35 at with bevel gearsf37 fixed to .transverse stub C85 shafts 38 rotatively mountedV in bearings'39 fixed to the side frame channels.

' Brackets 41 fixed tothe side frame inembers adjacent the vtransverse stub shafts have of the channels'to provide the floor 6b platform frame and pro- 65 ,tubular bearings .42 supporting short shafts w.

43l having bevel gears 44 .meshed with said (90 operating bevel gears 37 4and bevelgears 45 on theiroppositev ends meslied with Vthe platform supporting Vgears 23 at the front .endjof the platform.

The inwardly projecting vends of the stub (9x5.

shafts 33 are. journaled in bearings ,46 .offset from and supported on, arms 47 .projecting inwardly ofthe pitfrom thebrackets 33. order to effect rotation of thek operatin bevel gears 37 to rotate the several shafts an g dino gage the .platform .ment thereof.

posts, and -tinued rotation of the automobile wheels will, if desired effect movement of the automobile vfrom the rollers and'platform to the basement thus threadedly move the platform supporting gears on the threaded posts, I 'provide a pair of laterally spaced spur gears 50 keyed to the stub shafts between the bearings 39 and 46, and means presently described in driving relation with said gears whereby an automobile vmay move the platform. Parallel slightly spaced friction rollers 51 and A52 on shafts 53 are located in transverse slots formed in the outer end portion of the platform and supported in bearings "54 k'and 55 mounted on the upper edges of the side frame members. Gears 56 fixed to the roller shafts are meshed with said spur gears 50 whereby the rotating traction wheels of an automobile located on said rollers and frictionally engaging the same may effect rotation of the rollers and thus rotate the platform supporting gears on the threaded posts to move the platform vertically in the pit.

Attention is vcalled to the 4bevel gears 37 face in the same-direction, and are therefore located on opposite sides of the shaft bevel gears 36 and l44whereby the operating gears'r?. may effect rotation vof the shafts 34 and 43 in same direction.

Stop members 58 and 59 4preferably comprising plates fixed to the building wall and slightly inclined approach to the platform project short distances across the pit to enand check upward move- Guide channels 60 are mounted in vertical grooves 61 vformed in the side walls of the pit adjacent the middle lines of saidV walls and guide ribs fixed to the platform slidably engage in the grooves formed by said guide channels. to retain the platform in proper position in the pit and prevent binding of the threaded gears on the posts.

A roof 62 is preferably mounted on the .upper ends of the tubular standards to cover an automobile mounted on theplatform and also to cover the pit when the platform is lowered.

In using the invention, an automobile may ybedriven onto the platform and the driving `wheels stopped on the rollers. The engine of the automobile is thenoperated to rotate kthe wheels and effect rotation of the rollers, operating shafts and pl-atform supporting into thek pit to the level of the basement floor.

Engagement of the platform with the floor of thel pit will prevent further downward movement of the bevel gears on the threaded thus lock the rollers, whereby con- When rit is desired to move the automobile from the basement it may be driven ontok the platform and a pair ,of drive :wheels located on the rollers. The direction of rotation of aia tha.V the' the drive wheels will be reversed to effect reverse rotation of the platform supporting gears on the threaded posts for elevating the platform.

When the platform encounters the stop members, rotation of the gears and rollers will be prevented, and the automobile will piove from the platform to the ground surace.

The roofed platform movable in the pit 'thus provides a complete garage, whereby the automobile may be stored below the ground surface and protected, the use of long or steep driveways into basement garages and the many objectionable incidents to the presence of a depressed driveway, are avoided.

Vhat I claim and desire to secure by Letters Patent is:

1. A garage including a rectangular platform, vertical .threaded posts extending through said platform adjacent its corners, gears rotatively mounted on the platform and threaded on the posts, means for operably connecting the gears at each side edge of the platform including spaced aligning shafts, pinions fixed on the shafts and meshing with said gears, spaced aligning counter shafts on Vthe platform and having driving connection with said spaced aligning shafts, and common means operable by an automobile mounted on the platform for operating counter shafts to move the platform vertically on the posts.

2. A garage including a rectangular platform, a vertical threaded post extending through said platform'- adjacenteach of its corners, gears rotatively mounted on the platform and threaded on the posts, means for operably connecting the gears along each side ofthe platformV including spaced aligning shafts, pinions on the shafts meshing? with said gears, gear means for driving said shafts in opposite` directions, and means operable by anautomobile mounted on the platform for `operating said driving means to move the Yplatform vertically on the posts. y

- In testimony whereof I affix my signature.
